Magnachip Launches New Step-down Led Backlight Drivers

Both devices feature average-mode current control, programmable constant off-time, up to 3 V analog dimming input, and direct PWM dimming input. Operating from input voltage range of8.518 V, driversalso provide 1%current sense voltage accuracy, fault output, and short circuit protection. MagnaChip Semiconductor 1, Hyangjeong-dong, Hungduk-gu, Cheongju-si,Chungbuk, Korea (south) Original Press Release MagnaChip Launches New Step-Down LED Backlight Drivers Press release date: February 9, 2015 SEOUL, South Korea and CUPERTINO, Calif., MagnaChip Semiconductor Corporation ("MagnaChip") (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, today announced that it has launched two new step-down LED drivers targeting TV LED backlight and LED lighting applications. The new backlight drivers are designated as MAP3511 featuring single channel and MAP3512 featuring dual channels. The MAP3511 and MAP3512 drivers are new designs which replace the existing step-up power circuit method of LED TV backlighting with a step-down circuit. These solutions enable the optimization of TV backlight power circuits by reducing system cost, such as eliminating the need for additional external MOSFETs for dimming control, and increasing system efficiency. The new products have multiple embedded protection circuits preventing functional errors during LED operation. This also enhances TV image quality and performance.
